[QUOTE="Tanis143, post: 3188272, member: 43724"] Actually, thats incorrect to a degree. The older antennas were configured for VHF and UHF channels. When tv broadcasters started pushing out digital channels, then HD channels, they went with UHF as VHF didn't have the bandwidth for 1080i. That old antenna might pick up the channels, but it is not optimized for them now, hence the need for an amp. The antenna I built, while simple, picks up every single channel in Tulsa without an amp. This is similar to what I built. I just didn't use a reflector. You will need a couple of long pieces of at least 14 gauge copper wire (I used ground wire), a long enough board or a couple of pvc pipes put together with 4 elbows and a 300 ohm to 75 ohm matching transformer (the little block you would use to go from a coax to the two pigtails). Then its just the time to make it. [URL]http://pinosy.com/media/317574211215444200/[/URL] Here is a picture of the dimensions in US measurement. [ATTACH=full]129314[/ATTACH] There are other variations as well. This one was just the simplest to make. [/QUOTE]
